How to Choose
When selecting a mail order seed company for high germination rates, consider several key factors. First, look for companies that provide clear germination percentages on their seed packets or websites; this transparency reflects confidence in their seed quality. Second, check whether the company conducts regular germination testing and offers guarantees or replacement policies if seeds fail to sprout as expected. Third, consider the seed source and freshness—seeds stored for too long or shipped from distant locations without proper handling may have reduced viability. Finally, evaluate whether the seed varieties offered suit your climate and gardening goals, as even high-germination seeds must be appropriate for your conditions to thrive.
Frequently Asked Questions
Q: How long do seeds remain viable after purchase?
Most vegetable and flower seeds remain viable for 1-5 years depending on the species and storage conditions, but germination rates decline over time. Proper storage in cool, dry places extends viability.
Q: Do organic seeds have different germination rates?
Organic seeds often have germination rates comparable to conventional seeds if properly handled. High-quality organic seed companies conduct the same rigorous testing to ensure viability.
Q: Can I trust seed companies that don’t list germination rates?
Companies that don’t provide germination information may still offer good seeds, but transparent germination rates are a positive sign of quality control and reliability.
Q: What affects seed germination besides seed quality?
Environmental factors like soil temperature, moisture, and planting depth significantly influence germination success. Even high-quality seeds can fail if germination conditions aren’t optimal.
Q: Are heirloom seeds less viable than hybrid seeds?
Heirloom seeds generally have germination rates similar to hybrids when fresh and properly stored. The key difference lies in genetic diversity and seed saving, not viability.
Q: How do seed companies test germination rates?
They plant a sample of seeds under controlled conditions and record the percentage that sprouts within a set period, often 7-14 days, to estimate viability before sale.
